Hormaphidinae
Hormaphidinae is a subfamily of aphids (Aphididae) distinguished by complex life cycles involving gall formation on primary host plants and often host alternation. The subfamily includes three tribes—Cerataphidini, Hormaphidini, and Nipponaphidini—with approximately 50 genera distributed primarily in eastern and southeastern Asia, with some representatives in North America. Many species produce specialized sterile soldiers for colony defense and exhibit diverse gall morphologies, from simple leaf curls to elaborate multi-cavity structures.
